ADVERTISING-SIGN.

Specification of Letters Patent.

Patented July 5, 1921.

Application filed December 29, 1919. Serial No. 347,960.

' To all whom it may concern:

Be it known that I, DAVID STERNBERGH, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Advertising- Signs, of which the following is a specification.

My invention relates to advertising signs, and my object is to attract the attention of a passer-by due to the illusion of a moving element of the sign. The invention is fully described in connection with the accompanying drawing, and the novel features are pointed out in the claim.

Figure 1 indicates a preferred embodyment of my invention in connection with a pneumatic tire advertisement.

Figs. 2 and 3 are a diagrammatic elevation and a diagrammatic plan view respectively, indicating the illusionary effect of my invention.

Fig. 4 indicates diagrammatically a modification.

While the drawings indicate the application of my idea to one article ofadvertisement, it of course may be readily varied to suit different articles.

In the drawing I have indicated a main sign 2 which is shown in the preferred shape of a segment of a circle, and upon the outer face of which the advertising matter and a background appear; which in this case includes a path or roadway 3 along the upper edge.

Spaced to the rear and located approxi mately at theaxis of curvature of the segment of the main sign 2, is a cooperating sign 4, in this case a representation of a pneumatic tire in outline, which cooperating sign is elevated sutliciently to appear about resting on the top edge of the main sign 2 to the eye of a passing observer. This illusion is more clearly seen in Figs. 2 and 3, which indicate a vehicle 5 on an adjacent road, and the dotted lines representing the lines of vision. Fig; 2 indicates how the object 4: appearsalong the upper edge of the main sign 2, and Fig. 3 shows that the passing vehicle gives to the observer varying angles in the relation of the cooperating and main signs, so that it first appears'above one end of the main sign, position a, and apparently travels along the top to the other end, position b. This illusion of motion naturally attracts attention to the sign, enhancing its value, and in the preferred form indicated, the curved main sign and cooperating object sign are always in proper focus and not distorted to the eye of the passing observer.

Fig. l indicates a sign having an opening 6 through which the object behind may be seen, instead of appearing along the top edge, audit is obvious that other modifica tions may be readily devised. In some cases a flat sign may be employed, or the curved sign might be reversed and the cooperating sign located close to the ground in front, but approximately at the axis of curvature pref erably.

By locating my improved sign at advantageous points topographically, as in a clearing in the woods. or a curve, so as to cut off all vision except between the extreme lines of vision, positions a and 2), indicated in Fig. 3, a complete illusion may be obtained; and it may be designed to attract pedestrians, motor vehicles, or along railroad rights of way, the traveling passengers, by proper location and elevation of the main and cooperating parts. And the obvious ad vantages and adaptability for a multitude of various advertised articles will be readily seen.

hat I claim is:

A sign comprising a main board in the form of a segment of a circle and bearing the representation of a fixed background, and a cooperating board to the rear of said main board representing an object in motion, said cooperating board being located approximately at the axis of said segment and at a height to appear above the main board.

In testimony whereof I afiix my signature.

DAVID STERNBERGH.
